Audit frontend API calls against backend implementation for contract alignment and network shape. Use when "API audit", "FE-BE contract", or "review frontend API integration". Live 4xx/5xx reproduction → debug-fe-be-integration.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Frontend API Audit Skill
**Degree of freedom: MIXED** — Steps 0, 1, 3–6 `[HIGH freedom]`; Step 2
Sentry queries and schema SQL `[LOW freedom — run exactly]`.
Read-only. Present findings; the Phase 6 snippets are the fix shape to
recommend, not edits to make in this pass.
## How to reason
1. **Observe** — quote the FE call site, BE route, and response/error
2. **Interpret** — does the contract match (path, method, params, types)?
3. **Classify** — missing route / mismatch / untyped / cache-gap / correct
4. **Severity** — 404/401/type-mismatch in prod = Critical; cache/prefetch = opportunity
## Worked example
> **Observe:** `useUser` GETs `/api/users/${id}`; no `app/api/users/[id]/route.ts`;
> Sentry 25× 404 in 14d.
> **Interpret:** FE calls a route the BE never registered.
> **Classify:** missing route (Critical).
> **Severity:** Critical — guaranteed 404.
> **Finding:** `hooks/useUser.ts` | GET `/api/users/:id` | Critical | no BE route.
## Self-critique before reporting [LOW freedom — do not skip]
1. **Evidenced** — FE file + BE route or Sentry event, not "probably 500"
2. **Contract, not taste** — staleTime advice needs a freshness reason

How to install
mdr add kensaurus/skills/audit-fe-api@sha256:ea7d51f21b103fc3The line at the top of this page pins the label git:20261006.39320f8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
